Thank you, teachers!

I recently passed by a sign that said “I teach. What’s your superpower?”, and was reminded of the teachers that have been superheroes in my life. There were a few precious teachers who encouraged a shy little girl to love learning, changing the course of her life forever.  

In honor of Teacher Appreciation Week, we take a moment to say a big THANK YOU to superhero teachers, including the 30,000 teachers across the world that are using Khan Academy in their classrooms, and changing the lives of students.

We salute you as you endeavor to provide more personalized, mastery-based and interactive learning experiences for your students.  Thank you for putting in the long hours, for giving it your heart and soul, and for being a role model and an inspiration to students to be lifelong learners and explorers.
